Abstract
For the last decades the science of friction has received a great development. The processes of friction and wear substantially depend on the design of the units, the selection of wear-resistant materials, effective lubricants and their operation modes, as well as the operating conditions of the mechanisms, however, the lack of scientific ideas about the effect of the regime of the elastohydrodynamic friction regime on obtaining a high-quality surface layer of the workpiece, the influence of the elastohydrodynamic friction regime on the operational properties of the part, the influence of the volume-consumption regimes of the SM feed on the quality of the surface layer of the workpiece, by the rotational ironing method, has become the starting point for setting the goal Research. The purpose of the research is to study the frictional contact of an elastohydrodynamic lubrication lubricant operating as a method that allows obtaining a surface with a high class of purity. In this paper, the influence of the lubricant supply regimes at the moment of friction in the inter-roll contact is studied using the method of physical simulation of the contact interaction of a friction roller pair. The conditions under which a stable coating on the friction surfaces is formed preventing the abrasive wear of their surface layers is studied.
